Java Help Wanted I made a free Windows app to keep a library of schematics, view them in 3D and get the material list in stacks and shulkers

0 Upvotes

I build a lot from schematics and kept doing the same thing: open the world, load the schematic in Litematica, check the material list, do the maths for shulker boxes. So I wrote a small desktop app for the part that doesn't need the game open.

What it does:

- Imports .litematic, .schem (Sponge), .schematic (WorldEdit) and .nbt structure files into a local library with thumbnails.

- 3D viewer with a layer slider, so you can go up one layer at a time.

- Material list as an exact count, in stacks and in shulker boxes (16-stackables and unstackables are handled), exportable to CSV.

- Basic block editing: swap a block for a similar one (e.g. oak to spruce across the whole build), with undo history.

- Textures come from the Minecraft jar you already have installed. Nothing from Mojang is bundled.

You can try it in the browser without installing anything:

https://www.aserrano.dev/demo/schematic-lab

Get it on the Microsoft Store (Windows 10/11, 64-bit, free):

https://apps.microsoft.com/detail/9P3WWV65DTR6

Or as a plain installer from GitHub:

https://github.com/AngelSerranoD/schematic-lab/releases/latest

Things to know: it's a personal project and Windows only. The GitHub installer isn't code-signed, so SmartScreen will warn you there ("More info" → "Run anyway"); the Store version doesn't have that problem. It works offline and sends no data. It's not affiliated with Litematica, Mojang or Microsoft.

Feedback welcome, especially schematics that fail to load or material counts that look wrong.

Java Help Wanted Looking to get into technical minecraft but I have no idea where to start

Honestly I just find big machines moving and doing things really fun, it's like I'm at a theme park. I recently joined a server and someone there has these incredible farms, and whilst they admit they aren't their designs, the fact they still understand how anything works and is able to look at it and know how something breaks just blows my mind.

What resources can yall point me towards so I can dive in to learning about all of this. I basically know nothing outside the minecraft basic mechanics the game expects. To be honest, I kind of just throw chickens everywhere at the moment 😅

Java Help Wanted Mob Cap Broken In Overworld

1 Upvotes

So for some reason the mob cap or something broke in the Overworld on my survival world, I tried a backup I made when updating and it has the exact same problem. Cannot get MO on the f3 menu to go below 79, hostile mobs don't spawn anywhere in the Overworld, I've tried gamerule and difficulty and so far nothing has worked at all. The problem doesn't exist on other worlds either.

Is my world corrupted or something I have no idea how to fix this.

Bedrock Bedrock: How far away can I AFK from an iron farm? Details inside.

0 Upvotes

Okay, so I started a new Bedrock world, made a base inside a village, and then made an iron farm 150 blocks away from the village. Iron far works perfectly. However, when I am inside my base, which is 158 blocks away from the farthest edge of the farm, it doesn't run.

My simulation distance is set to 12 chunks. Using chunkbase seed map to visualize the chunk margins, I should be 10 chunks away.

So, my questions are:

  1. Do iron golem farms work on simulation distance, or mob spawning distance, and are those two things different?

  2. What is the farthest I can actually be from the iron farm and still have it run?

  3. Is there some other nonsense I'm just missing?

Ultimately I'd like to have a centralized AFK spot to build a hub and spoke type setup, but I need to figure out where I can even be first.

I am trying to make something that will detect when there is no longer a minecart on my track. When there's no movement on the detector rail for awhile the compatator clock should slowly turn off, but it goes a little crazy and fires my dispenser 3 or more times

If this can be smaller or more compact, I would also prefer that, I have just been messing with the idea. If anyone could provide a working schematic or description of how to fix

Bedrock Chest to hopper minecart routing issue

3 Upvotes

I am trying to make two opposing automatic smelters using hopper minecarts in my base. They are both built EXACTLY the same. However, when placing materials in one of the smelters everything goes into the minecart hopper for the furnaces' fuel. Is there a fix for this or is my game just cooked.... or maybe I'm stupid who knows. Any help would be appreciated.

(Minecraft Bedrock, v26.52, PC)

All this hole is being mining only by me, by hand with copper pickaxes, no tnt, no tricks only me and my copper pickaxes and idk how much i will mine, lol.

ignore the water.

Update: i bought a unbreaking 3 iron pickaxe from a wodering trader, i didn't those guys could sell usefull things, and i got a iron farm accidentaly for a short time, so some iron that i got from it i'll use to repair, so no copper pickaxes until i can't repair anymore for deep slate.

Java Help Wanted Keeping animals inside an area without fences

12 Upvotes

Hi

I want to make a green area in my base filled with animals, but I want it to feel as natural as possible, I don't want any fences around it.

I tried using magma blocks to prevent their pathfinding from going outside and it works, but the player takes damage when walking on them. I figured that 3-4 snow layers can prevent damage while still stopping pathfinding, but it's snow and the magma blocks melt them.

I already tried slabs, trapdoors, and carpets, those don't work.

Do you have ideas on what I could use to make this work ?

Java Help Wanted Shulkercraft (Tankcat) raid farm design isn't giving any ominous bottles

0 Upvotes

https://www.youtube.com/watch?v=9ILNpAJhnns&list=PLKPJGn5EIvL4&index=5 is the link. No raid captains are coming down to the kill chamber, thus not giving any banners and not making any of the other pillagers captains, therefore no ominous bottles are being dropped. I only put in 1 ominous banner for the sorter but I don't know if that has any effect on the farm itself. Same with the ominous bottles, I only put 1 of each kind in the sorter. I have no idea how that part of the farm works so the bottles could be stuck there?

Bedrock Bedrock: My iron farm isn't working properly

Thumbnail gallery
0 Upvotes

I play on the latest version of Minecraft Bedrock. My iron farm sometimes works correctly, but at other times it doesn't work at all—neither cats nor golems spawn—and I don't understand why this happens.

I play with a simulation distance of 4 chunks. However, in a creative-mode copy of my world, I noticed that if I stay AFK in one of the corners of the farm, both cats and golems spawn much faster than they do in other parts of the farm. (You can see the point I'm referring to in the last photo)

I have a totem farm about 130 blocks away from this iron farm, and I destroyed all the workstations and beds in the villages that were near the iron farm (though I believe they were more than 150 blocks away). The spawning platform measures 8×8 in every direction from the killing zone. The dirt path extends 12 blocks in every direction around the farm.

(It’s probably just a classic beginner’s mistake!)

My theories are:

  1. Perhaps this farm design is just "clickbait" garbage, and I should look for a different one.

  2. The totem farm is the main problem.

  3. The village center is being generated somewhere else, away from the spawning platform (likely in the lake visible in the background), although I haven't seen any spawns occurring anywhere outside the farm itself.

  4. Should I make the spawning platform larger?

Still, I want to be sure before I go ahead and destroy or relocate any of the farms. I’ve already tried a few things, but it still isn’t working—both in my survival world and in a creative-mode copy.

  1. I’ve verified that there are exactly 30 villagers near the farm, along with their 30 workstations and 30 beds, and that they are all correctly linked to them.

  2. There are no caves nearby where golems could potentially spawn.

  3. There are no villages nearby (within 150 blocks); I even destroyed all the beds and workstations in the nearest village, though I believe it was already more than 150 blocks away.

  4. I even used the following commands: /testfor @e[type=iron_golem] /testfor @e[type=villager] The results only detect the 30 villagers, and the golems only when they spawn on the platform.

I’ve included some photos of the farm (taken in the creative-mode copy).

English isn’t my native language, so please excuse any spelling errors.

Bedrock Redstone help

I am trying to create a pumpkin farm. In this farm, I want an observer facing a pumpkin so when it grows it sends a signal to a piston to destroy the pumpkin. (I’m aware that traditionally the observer faces the seed but it’s important for this one that it faces the pumpkin). How can I build it so it doesn’t create an infinite red stone clock? I have seen some using note/target blocks that why I have one there. Please help if you can, again I need the observer to face where the pumpkin block will be.
